Charging Profile of our Lithium Batteries…

This shows the typical charging profile of our Solar/Lithium DC power system on sunny days at anchor.

The loads discharge the system at night and usually by early afternoon the LiFePO4 (Lithium Oxide) batteries are back up to 100% SOC (state of charge).

The orange line shows the amperage “in” and “out” of the system.

The blue line is SOC.

It is noteworthy that the recharge rate with this type of battery chemistry is so fast. The other advantage is that it is OK to discharge these down to, say, 10% or so without shortening their longevity. Both are features that are advantageous over lead acid chemistry.

It is 12:42pm and I am a little surprised that we have not popped up to 100% SOC yet, on this sunny day. But, we have been running the microwave a bit more than usual.

This shows a snapshot of the solar controller status of the 3 aft PV (photo voltaic solar) panels. The “network total power” is the combined watts including a 4th PV panel that is up forward on its own solar controller.
It looks like our LiFePO4 bank “popped” to 100% SOC around 3:30pm today. The forward PV panel has been in a shadow for a while now.
